The impact of percutaneous coronary intervention using the novel dynamic coronary roadmap system

Abstract

The dynamic coronary roadmap (DCR) is a novel technology that creates a dynamic, motion-compensated, real-time overlay of the coronary arteries on a fluoroscopic image. Whether the DCR reduces contrast volume and enables safe and effective treatment was examined. A total of 146 patients undergoing percutaneous coronary intervention (PCI) from June 2017 to September 2017 in our hospital were retrospectively evaluated. Chronic total occlusion lesions, acute coronary syndrome, and hemodialysis patients were excluded. Patients were divided into the control group (PCI without DCR, 92 patients, 103 lesions) and the DCR group (38 patients, 43 lesions). The primary endpoint was contrast medium volume, and secondary endpoints were radiation dose, fluoroscopy time, and clinical success rate. There was no significant difference in the success rate (100% vs. 100%, P = 1.000) between the groups. Fluoroscopy time (16.3 ± 11.2 min. vs. 11.4 ± 5.5 min, P = 0.007) and contrast medium volume (152.1 ± 73.0 ml vs. 118.8 ± 49.7 ml, P = 0.006) were significantly lower in the DCR group than in the control group. DCR use during PCI was associated with a significant reduction in contrast volume and fluoroscopy time compared to a control group despite similar clinical, lesion, and procedural characteristics.
